  • Refractory Gold Processes Mineral Processing & Metallurgy

    Gold can be leached and extracted/recovered in several ways Even if you gold is “refractory” in pyrite or arsenopyrite, you can still get much value from your ore/rock depending on the economics of capital and operating cost The cheapest and fastest option is to simply grind and CIL the whole thing according the the process flowsheet here shown The next option, once you have confirmedOre A contained approximately 61 pct arsenopyrite and 9 pct pyrite, and ore B contained 35 pct arsenopyrite and 24 pct pyrite The lowgrade ore contained only 1 pct arsenopyrite and 5 pct pyrite Scanning electron microscopy analysis and Xray diffraction patterns of the ores indicated that virtually all of the arsenic was present as arsenopyriteArsenic Pyrite Gold Extraction by Alkaline Leaching Oxidation
